INCANDESCENT GAS-BURNER FOR HYDROCARBON LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 621,333, dated March 21, 1899.

Application filed January 20, 1898- Serial No. 66 7,297. (No model.)

To all, whom it may concern: the top of the body A. At the base of the Be it known that I, PETER J. FITZGERALD, collar is an aperture a, and adjacent to the a citizen of the United States, residing at Bosaperture is the closed innerend of the extenton,inthe countyof Suffolk and State of Massion a, which end is shaped to provide a sachusetts, have invented certain new and curved surface a From the extension prouseful Improvements in Incandescent Gasjects a plate a the inner side of which is a Burners for Hydrocarbon Liquids; and I do continuation of the surface a Fitting on declare the following to be a full, clear, and the collar (1 is a cap-piece d, which may have exact description of the invention, such as frictional engagement with the collar or may,

10 will enable others skilled in the art to which as shown, be screwed onto the latter, and said it appertains to make and use the same, refcollar is provided with an aperture d, which erence being had to the accompanying drawregisters with the aperture a. The upper ings, and to the letters of reference marked end of the cap is perforated, or, in lieu of perthcreon, which form a part of this specificaforations, a wiregauze may be employed.

I 5 tion. In the chamber is a baffle-plate 6, preferably This invention relates to the class of incan' convex in cross-section and centrally aperdescent gas-burners which are adapted for tured and supported above the apertu re a by the consumption of hydrocarbon liquids, such arms 6 e, which rest on the upper end of the as naphtha, gasolene, and thelike; and it concollar (1 The body A is provided with in- 20 templates theprovision of animproved structegral arms a", to which the chimney-sup- 7o ture of burner capable of obtaining high effiport is attached, and also with an apertured ciency and reliability in operation and which lug a l and set-screw f for the attachment of possesses the further very desirable advanthe mantle-support g. I tage of being simple in construction, and At h is shown a cup for containing the liq- 2 5 hence cheap to produce. uid by the ignition of which the preliminary The nature of the invention will be found heating of the burner is obtained. This cup to be fully and clearly set forth in the followmay, however, be'dispensed with, as the preing detailed description, which is to be read liminary heating may be effected by the use in connection with the accompanying drawof a suitable torch.

3o ings. In practice the liquid enters the passage a In the said drawings, Figure 1 is a plan through the extension Ct, and the valve 0 beview of a burner embodying my invention, ing opened the cuph is partially filled, after and Fig. 2 is a'vertical central sectional View which said valve is closed. The contents of of the same. the cup are then ignited, and the heat pro 35 Referring to the said drawings by letter, A duced vaporizes the liquid contained in the denotes the body of the burner, which is propassages referred to. The valve 0 is then vided with an interiorly-threaded extension again opened and the vapor passes into the Ct for connection with the liquid-supply pipe passage a being mixed with air, and is igh and with an inclined passage (1, leading nited at the cap-piece d. The ignited vapor 40 from said extension downwardly to a vertical fills the chamber a and a small jet of flame 9o passage c also provided in said body, the is projected through the aperture (1 and imlatter passage being controlled by a needlepinges against the curved surface a and valve 0, the threaded stem 0 of which engages thereby supplies the heat necessary for the interior threads formed in an integral extencontinuous vaporization of the liquid. The

45 sion at". In vertical alinement with the pasfunction of the baffle-plate is to check the sageta is a passage a of comparatively large flow of vapor sufficiently toallow of the fordiameter, the lower end of which is open to mation of the vaporizing-jet, and in addition the atmosphere for the admission of air, and to said plate I may employ an apertured disk which at its upper end communicates with a t' to contract the opening from the passage- 50 chamber a, formed by an integ l collar on at into the chamber. Obviously the size of the Ice aperture in the disk, as well as of the aperture in the plate 6, may be varied as circu mstances demand.

The aperture (1 in the cap-piece (1 may be dispensed with where said cap-piece is screwed onto the collar, and in lieu thereof the lower edge of the cap-piece may come above the aperture a or may be moved topartly close the latter to adjust the size of the vaporizerflame.

I claim as my invention- 1. An incandescent gas-burner for hydrocarbon liquids, comprising a body having an apertured extension, a passage leading from the extension downwardly into a vertical passage, a valve in the latter passage, a cylindrical chamber in the vertical passage having an opening through which ignited vapor. is projected against the wall of the extension, and a baffle-plate supported in the chamber between said opening and the burner-opening, substantially as described.

2. An incandescent gas-burner for hydrocarbon liquids comprising a body having an apertured extension, the inclined passage a leading from the extension downwardly into the valved vertical passage a the vertical passage a the chamber a? forming a c0ntinuation of the passage a and provided with the aperture ed, the cap-piece d adjustable to control the aperture, and the apertured disk i and baffle-plate e in said chamber, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

PETER J. FITZGERALD.
